Halfway Between 20 and 486

When you ask "What number is halfway between 20 and 486?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=486.

Halfway Between Line

To find the number halfway between 20 and 486, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 486 into our formula, we get:

(20 + 486)/2 = 253

Thus, the number halfway between 20 and 486 is 253.

To check that our answer is correct, we subtract 20 from 253 and subtract 253 from 486 and compare the two numbers:

253 - 20 = 233
486 - 253 = 233

As you can see, the halfway number is 233 higher than 20 and 233 lower than 486. Therefore, our halfway between answer of 253 above is correct.
